To keep users from viewing records that they are not authorized to view, you can set up Record Level Access control to limit their access to only specific records in the table. See "Editing record access privileges" in FileMaker Help and check out this particular sub section: "Entering a formula for limiting access on a record-by-record basis" for a description of how to set this up.
And a script can either set up your layout with a new blank record or a found set of zero records to keep existing records from being initially visible.
